Hi,

I have some question about this. I succeed to override the preFeatureInsert 
and succeed to change the style for all feature (which is not my final 
purpose).

I would like to use a sld webservice for my layer, how can I use the sld 
content in the preFeatureInsert? Here my code:
/****************************************
	function HbsVector() {
		this.preFeatureInsert = function(feature) {
		    this.style.fillOpacity = 1;
		   this.style.fillColor= "#0000FF";
		   this.style.graphicOpacity = 1;
		   this.style.strokeColor= "#0000FF";
		   this.style.strokeWidth = 3;
		   this.style.pointRadius = 6;

		   OpenLayers.Feature.Vector.style['default'] = this.style;
		}
	}
	HbsVector.prototype = new OpenLayers.Layer.Vector();
	var HbsGML = new HbsVector();
	HbsGML.preFeatureInsert();
	
	var gml = new OpenLayers.Layer.GML("GML", "data.gml,{sld:"navitia.sld", 
transparent:'true'});
/****************************************

Thanks,

Y.
